Hi everyone. I am new to the forum and have a few question about the newest member of my vehicle stable. I just bought an '04 LS Tahoe with 70K miles. It's a one owner and I got it for about 5k under retail. I think I got a deal. Anyway, my questions were about interior lighting. I think I have two bulbs burned out. The tuning knob on the radio does not light up and the panel where my headlight/dome light button does not light up. Should they? And how hard would it be to replace these by myself? Thanks for the answers in advance.
